On the use of low and high cycle fatigue damage models

In this paper, Continuum Damage Mechanics (CDM) theory is applied to low cycle and high cycle fatigue problems. Damage evolution laws are derived from thermodynamic principles and fatigue number of cycles to crack initiation is expressed in terms of the range of applied stresses, triaxiality functio...
